Couplings & materials
Technological precision for demanding applications
Our couplings are designed to ensure backlash-free torque transmission even under heavy loads. By using machining production methods, we achieve particularly tight tolerances, high fitting accuracy and precise rotational stability. This applies equally to safety couplings, shaft couplings and quick couplings.
- Maximum power transmission with high torsional rigidity
- Low-vibration performance thanks to vibration-damping geometry
- Long-lasting operational reliability even under continuous dynamic loads
Our connecting elements are designed for optimum force distribution and reliably compensate for shaft misalignment. This creates the best conditions for use in high-speed applications or in
Material selection for maximum performance
The materials of our couplings are designed for durability, corrosion resistance and mechanical properties. Depending on the requirements, we combine high-quality metals, special alloys or engineering plastics to ensure long-lasting functionality.

Frequently asked questions
Different types of couplings are used in mechanical engineering – depending on the requirements. Shaft couplings, backlash-free elastomer couplings, metal bellows couplings and safety couplings for overload protection are frequently used. The selection depends on the torque, displacement, speed and operating environment.
The right coupling is selected on the basis of torque, shaft diameter, misalignment and ambient conditions such as temperature or humidity. Our experts will advise you individually and help you select the optimum solution for your design.
Safety clutches interrupt torque transmission as soon as a defined limit is exceeded. This reliably protects sensitive parts and machine components from damage – especially in robotics, conveyor technology or aviation.
Depending on the application, u-Flex uses high-strength aluminum alloys, stainless steel, titanium or special materials such as Inconel. These materials offer an ideal combination of strength, corrosion resistance and machinability.
Our couplings reliably compensate for axial, radial and angular shaft misalignment. Depending on the design, the tolerance is up to ±0.75 mm with an angular misalignment of 5 degrees. This ensures smooth running and protects the bearings.
Yes, our backlash-free spiral clutches are maintenance-free, as they are manufactured from a single piece and contain no moving wearing parts. They require neither lubrication nor readjustment and are ideal for long-term applications.
